Description

Technical Field

[0001] This application relates to the field of optical communication technology, and in particular to an optical fiber protector. Background Technology

[0002] With the gradual development of the optical distribution network (ODN) industry, home services are becoming increasingly common. By directly connecting optical fibers to indoor spaces, people can enjoy the ultimate experience of new services brought about by the rapid development of networks in every room of their homes.

[0003] However, in order to improve the aesthetics and concealment of fiber optic installations, the fiber optic cables are usually laid close to or through walls. This inevitably requires bending the fiber optic cables, which increases the risk of fiber breakage and affects the transmission of optical information. Utility Model Content

[0004] This application provides an optical fiber protector that can solve the technical problems existing in related technologies.

[0005] This application provides an optical fiber protector, which includes a fixed structure and a fiber compression structure.

[0006] The fixing structure is used to attach to or pass through the wall. The fiber-pressed structure is connected to the fixing structure, and the fiber-pressed structure is in abutting contact with at least one optical fiber, such that at least one optical fiber extends in a direction close to the wall.

[0007] With the above arrangement, the fiber optic protector can be connected to or pass through the wall using a fixed structure, and the fiber compression structure connected to the fixed structure can be used to press the fiber optic cable against the wall so that it extends in a direction close to the wall. This allows the fiber optic cable to be laid close to or through the wall, avoiding the fiber optic cable from sticking up, improving the aesthetics and concealment of the indoor fiber optic cable layout. Moreover, the fiber compression structure can minimize the bending of the fiber optic cable at small angles, effectively reducing the risk of fiber optic cable breakage, improving the reliability of the fiber optic cable, and ensuring the transmission performance of optical information.

[0008] In one implementation, there are multiple optical fibers arranged in parallel, each capable of making pressure contact with the fiber compression structure.

[0009] In one implementation, the surface of the fiber pressing structure used to press the optical fiber is provided with at least one fiber pressing groove, and each fiber pressing groove can accommodate one or more optical fibers. In this way, when the fiber pressing structure presses the optical fiber against the wall, the optical fiber cannot move in a direction parallel to the wall.

[0010] In one implementation, the fixing structure and the fiber-pressed structure are both plastic structural components. The fixing structure and the fiber-pressed structure can be an integral structure or a separate assembled structure.

[0011] In one implementation, the surface of the fixing structure facing the wall is provided with an adhesive layer, and the fixing structure is bonded to the wall through the adhesive layer.

[0012] With the above arrangement, the fixed structure can be easily and quickly bonded to the wall using the adhesive layer.

[0013] In one implementation, the fiber compression structure includes a pressure section located on one side of the fixed structure and spaced apart from the fixed structure. A fiber passage is formed between the pressure section and the fixed structure, and at least one optical fiber can pass through the fiber passage to the space between the pressure section and the wall to extend in a direction close to the wall.

[0014] With the above arrangement, a fiber passage channel is formed by the pressure-resistant parts arranged at intervals between the fiber compression structure and the fixed structure. After the optical fiber extends along the side of the fixed structure away from the wall, it can pass through the fiber passage channel to the space between the pressure-resistant parts and the wall. The fixed structure can support the optical fiber on the side away from the wall. This is particularly effective for use in both external and internal corners. In the external corner use, sharp corners may cause wear to the optical fiber. In the internal and external corner use, the optical fiber needs to face the problem of small-angle bending. The fixed structure can cover the external or internal corners and build a bending support surface with a larger angle on the external or internal corners. The optical fiber can bend at a larger angle along the fixed structure to pass through the external or internal corners. Moreover, it can be used in conjunction with the fiber compression structure to fix the position of the optical fiber.

[0015] In one implementation, the surface of the fixed structure away from the wall is provided with at least one fiber optic slot, each of which can accommodate one or more optical fibers. Thus, when the optical fibers are laid along the surface of the fixed structure away from the wall, the optical fibers cannot move along the surface of the fixed structure.

[0016] In one implementation, the fixing structure is a rectangular plate, and the surface of the fixing structure facing away from the wall is a streamlined surface. The streamlined surface is more conducive to the laying of optical fibers and is also more aesthetically pleasing.

[0017] In one implementation, the fiber channel has an opening through which at least one optical fiber can enter and exit the fiber channel.

[0018] With the above arrangement, the optical fiber can be directly inserted into the fiber channel through the opening without having to pass one end of the optical fiber through first. This greatly improves the efficiency of the optical fiber protector and allows for easy addition or reduction of the number of optical fiber protectors in the middle of the already laid optical fiber, further improving the efficiency of indoor optical fiber deployment.

[0019] In one implementation, the fiber pressing structure further includes a first connecting portion, which extends in directions close to and away from the fixed structure, with one end of the first connecting portion connected to the fixed structure and the other end of the first connecting portion connected to the pressing portion, the extending direction of the pressing portion being arranged at an angle to the first connecting portion.

[0020] With the above arrangement, the pressure part is connected to the edge of the fixed structure through the first connecting part. The pressure part only needs to be arranged at the end of the first connecting part away from the fixed structure. Moreover, by arranging the pressure part and the first connecting part at an angle, the size of the pressure part in the direction perpendicular to the optical fiber extension can be extended, so that the pressure part can achieve pressure contact of more optical fibers.

[0021] In one implementation, the angle between the extending direction of the pressing part and the first connecting part ranges from 60 to 120 degrees. In another implementation, the angle between the extending direction of the pressing part and the first connecting part is 60 degrees, 75 degrees, 90 degrees, 105 degrees, 120 degrees, etc.

[0022] In one implementation, the first connector is elastic and can provide the pressing part with an elastic force toward the wall, so that the pressing part can press the optical fiber tightly against the wall, resulting in a better fiber pressing effect.

[0023] In one implementation, the fixing structure, the first connecting part, and the pressing part are an integral injection-molded structure.

[0024] In one implementation, the first connecting part is located at one end of the pressing part, and the other end of the pressing part and the fixing structure are arranged at intervals. The pressing part, the first connecting part and the fixing structure together form a fiber passage with an opening.

[0025] In one implementation, the extension direction of the first connecting part is perpendicular to the edge of the corresponding fixing structure, the extension direction of the pressing part is perpendicular to the extension direction of the first connecting part, and the extension direction of the pressing part is parallel to the edge of the corresponding fixing structure.

[0026] With the above arrangement, the pressure part, the first connecting part and the fixing structure together form a fiber passage channel with an opening. The optical fiber is laid along the surface of the fixing structure facing away from the wall. The opening can be used to insert the optical fiber into the fiber passage channel. The optical fiber is then pressed between the pressure part and the wall, making the operation more convenient and improving the efficiency of the optical fiber protector.

[0027] In addition, the first connecting part and the pressing part are arranged perpendicular to each other, and the pressing part is parallel to the edge of the fixed structure. The position of the opening part is relative to one side edge of the fixed structure. The optical fibers laid along the surface of the fixed structure away from the wall can all pass through the fiber channel and be pressed against the wall by the pressing part.

[0028] In one implementation, fiber pressing structures are provided on opposite sides of the fixed structure, at least one optical fiber is located on the surface of the fixed structure facing away from the wall, and the two ends of the at least one optical fiber are pressed against the opposite sides of the wall by the two fiber pressing structures.

[0029] With the above arrangement, fiber compression structures are arranged on opposite sides of the fixed structure to press down on both ends of the optical fiber laid along the surface of the fixed structure away from the wall. This not only allows the optical fiber to be fixed to the flat wall using fiber optic protectors, but also provides support and protection for the bent section of the optical fiber, especially at external or internal corners. The fiber compression structures on both sides press down on both ends of the optical fiber, keeping it in a bent state, and allowing both ends of the optical fiber to extend in a direction close to the wall, preventing the optical fiber from curling up on both sides of the external or internal corner.

[0030] In the fiber optic protector of this embodiment, the fiber compression structure can be arranged only on one side of the fixed structure, or it can be arranged on opposite sides of the fixed structure. The former can realize the compression and fixation of the fiber on a flat wall, while the latter can not only realize the compression and fixation of the fiber on a flat wall, but also realize the compression and fixation of the fiber at the external corner and the internal corner.

[0031] In one implementation, the fixing structure includes a first fixing part, a second fixing part, and a second connecting part; the first fixing part and the second fixing part are movably connected through the second connecting part, and the first fixing part has a fiber pressing structure on the side facing away from the second fixing part, and the second fixing part has a fiber pressing structure on the side facing away from the first fixing part.

[0032] With the above arrangement, the fixing structure is a deformable structure composed of a first fixing part, a second fixing part, and a second connecting part. It can conform to the shape of the wall and the corner. For example, when it is necessary to fix the optical fiber to a flat wall, an external corner, or an internal corner, the first fixing part and the second fixing part rotate relative to each other around the second connecting part, presenting different shapes to meet the fiber compression requirements of different wall usage scenarios.

[0033] In one implementation, the fiber optic protector includes a straight-angle usage state, a positive-angle usage state, and a negative-angle usage state.

[0034] In the flat usage state, the first fixing part and the second fixing part remain flat, and the first fixing part and the second fixing part can be simultaneously bonded to the same flat wall surface. The fiber optic protector can fix the fiber optic cable to the flat wall surface.

[0035] When used at the external corner, the first fixing part and the second fixing part rotate relative to each other around the second connecting part, forming an inner right angle structure. The first fixing part is bonded to one side of the wall of the external corner, and the second fixing part is bonded to the other side of the wall of the external corner. The second connecting part is bent on the edge of the external corner to connect the first fixing part and the second fixing part. The fiber optic protector can fix the fiber optic cable to the external corner.

[0036] When used in the inside corner, the first fixing part and the second fixing part rotate relative to each other around the second connecting part, forming an external right angle structure. The first fixing part is bonded to one side of the wall of the inside corner, and the second fixing part is bonded to the other side of the wall of the inside corner. The second connecting part is bent on the edge of the inside corner to connect the first fixing part and the second fixing part. The fiber optic protector can fix the fiber optic cable to the inside corner.

[0037] In one implementation, the first fixing part can be separated from the second fixing part along the second connecting part, so that the first fixing part and its connected fiber pressing structure, as well as the second fixing part and its connected fiber pressing structure, are used as two fiber optic protectors respectively.

[0038] In one implementation, the first fixing part, the second connecting structure, the second fixing part, the fiber pressing structure connected to the first fixing part, and the fiber pressing structure connected to the second fixing part are all integral injection molded structures.

[0039] In one implementation, the fixing structure includes a flared portion and a tubular portion, which are coaxially connected and their axes are perpendicular to the wall. At least one optical fiber passes sequentially through the flared portion and the tubular portion to pass through the wall. The fiber-pressing structure is disc-shaped, and its edge is connected to the edge of the flared portion via a third connecting portion. The fiber-pressing structure can be rotated around the edge of the flared portion via the third connecting portion. When the fiber-pressing structure is installed over the flared portion, it can press and bend at least one optical fiber, causing at least one optical fiber to extend in a direction close to the wall.

[0040] With the above arrangement, when the fixing structure is connected to the wall, the tubular part is inserted into the wall at an angle perpendicular to or at an angle to the wall, while the flared end remains outside the wall. Furthermore, the circumferential edge of the flared end fits snugly against the wall, allowing the fixing structure to be anchored using the friction between the tubular part and the wall. The optical fiber can pass through the flared end into the tubular part and extend along its inner edge until it passes through the entire wall, achieving through-wall fiber deployment. A disc-shaped fiber-pressing structure is arranged at the flared end. This structure, in conjunction with the flared end, can compress the axially extending optical fiber into a radial extension along the flared end. Moreover, the optical fiber can be bent along the internal curve of the flared end at a relatively large angle, without the risk of breakage.

[0041] In addition, the third connection part is located at the edge of the horn mouth. The fiber pressing structure is connected to the horn mouth through the third connection part. When the horn mouth is open, the fiber pressing structure is flipped to the outside of the horn mouth, which will not hinder the fiber insertion operation of the horn mouth.

[0042] In one implementation, the fiber pressing structure is further provided with a first snap-fit ​​part and the flared mouth part is provided with a second snap-fit ​​part. When the fiber pressing structure is covered on the flared mouth part, the first snap-fit ​​part and the second snap-fit ​​part snap-fit ​​each other.

[0043] With the above arrangement, when the fiber pressing structure is covered by the horn mouth, the first and second snap-fit ​​parts are used to snap and fix the fiber pressing structure on the horn mouth, which can prevent the stress of the optical fiber from pushing the fiber pressing structure open, and at the same time provide fiber pressing support force for the fiber pressing structure.

[0044] In one implementation, the fixing structure further includes anchoring fins located on the outer wall of the tubular portion.

[0045] With the above arrangement, the tubular section can be anchored to the wall using the anchoring fins on the outer wall, thereby improving the reliability of the connection between the fiber optic protector and the wall.

[0046] In one implementation, at least one of the fiber pressing structure and the flared opening is provided with a support portion. When the fiber pressing structure is covered by the flared opening, the support portion supports the fiber pressing structure and the flared opening, so that a fiber passage space parallel to the wall is formed between the fiber pressing structure and the flared opening.

[0047] In addition, to prevent the fiber compression structure from being overly compressed, a support is arranged between the fiber compression structure and the flared end. The support can support the two to form a fiber passage space, from which the optical fiber can extend outward along the direction close to the wall.

[0048] In one implementation, the fixing structure further includes a notch or groove that extends axially along the flared end and the tubular portion, respectively penetrating the flared end and the tubular portion. When the fiber pressing structure is applied to the flared end, the first snap-fit ​​portion is inserted into the notch or groove on the flared end and snaps into place therein, and the notch or groove on the flared end forms a second snap-fit ​​portion.

[0064] Combination Figure 1 , Figure 4 and Figure 6 As shown in the embodiment of this application, an optical fiber protector is provided, which includes: a fixing structure 1 and a fiber compression structure 2; the fixing structure 1 is used to connect to the wall 200 or pass through the wall 200.

[0065] The fiber pressing structure 2 is connected to the fixed structure 1, and the fiber pressing structure 2 is in abutting contact with at least one optical fiber 100, so that at least one optical fiber 100 extends in the direction of being close to the wall surface 200.

[0066] With the above arrangement, the fiber optic protector can be connected to or pass through the wall 200 using the fixed structure 1, and the fiber pressing structure 2 connected to the fixed structure 1 can be used to press the fiber optic cable 100 into a direction that is close to the wall 200. This allows the fiber optic cable 100 to be laid close to or through the wall, avoiding the fiber optic cable 100 from sticking up, improving the aesthetics and concealment of the indoor fiber optic cable 100 installation. Moreover, the fiber pressing structure 2 can minimize the bending of the fiber optic cable 100 at small angles, effectively reducing the risk of fiber optic cable 100 breakage, improving the working reliability of the fiber optic cable 100, and ensuring the transmission performance of optical information.

[0067] In some examples, there are multiple optical fibers 100, which can be arranged in parallel and can make pressure contact with the fiber pressing structure 2 respectively.

[0068] In some examples, the surface of the fiber pressing structure 2 used to press the fiber 100 is provided with at least one fiber pressing groove (not shown in the figure), and each fiber pressing groove can accommodate one or more fibers 100 respectively. In this way, when the fiber pressing structure 2 presses the fiber 100 against the wall 200, the fiber 100 cannot move in a direction parallel to the wall 200.

[0069] In some examples, there are multiple fiber compression slots, which can be arranged parallel to each other, spaced apart, non-parallel, or intersecting. When multiple fiber compression slots are arranged parallel to each other, they can each accommodate multiple fibers 100 arranged in a parallel and spaced manner. When multiple fiber compression slots are non-parallel or intersecting, they can each accommodate multiple fibers 100 arranged in a non-parallel or poorly arranged manner. Therefore, the fiber optic protector offers greater flexibility in use and can meet the deployment needs of more fibers 100.

[0070] In some possible implementations, the fixing structure 1 and the fiber pressing structure 2 are both plastic structural components. The fixing structure 1 and the fiber pressing structure 2 can be an integral structure or a separate assembled structure.

[0071] In some examples, the surface color of the fiber optic protector matches the color of the wall 200, which helps to further improve the aesthetics and concealment of the indoor fiber optic 100 installation.

[0072] Combination Figure 4 As shown, in some embodiments, the surface of the fixing structure 1 facing the wall 200 is provided with an adhesive layer 11, and the fixing structure 1 is bonded to the wall 200 through the adhesive layer 11. With the above arrangement, the fixing structure 1 can be conveniently and quickly bonded to the wall 200 using the adhesive layer 11.

[0073] In some examples, the adhesive layer 11 is a double-sided adhesive. Before use, the double-sided adhesive layer is first adhered to the fixing structure 1. When it is necessary to connect the fixing structure 1 to the wall 200, the release paper on the double-sided adhesive layer is peeled off, and the fixing structure 1 can be adhered to the wall 200.

[0074] Combination Figures 1 to 4 As shown, in some embodiments, the fiber pressing structure 2 includes a pressing part 21, which is located on one side of the fixed structure 1 and is spaced apart from the fixed structure 1. A fiber passage 23 is formed between the pressing part 21 and the fixed structure 1, and at least one optical fiber 100 can pass through the fiber passage 23 to the space between the pressing part 21 and the wall 200 to extend in the direction close to the wall 200.

[0075] With the above arrangement, a fiber passage channel 23 is formed by the pressure-blocking part 21 arranged at intervals with the fixed structure 1 in the fiber-pressing structure 2. After the optical fiber 100 extends along the side of the fixed structure 1 away from the wall 200, it can pass through the fiber passage channel 23 and pass between the pressure-blocking part 21 and the wall 200. The fixed structure 1 can support the optical fiber 100 on the side away from the wall 200. This is particularly effective for use in both external and internal corners. In the external corner use, sharp corners may cause wear to the optical fiber 100. In both external and internal corner use, the optical fiber 100 needs to face the problem of small-angle bending. The fixed structure 1 can cover the external or internal corner and build a bending support surface with a larger angle on the external or internal corner. The optical fiber 100 can bend at a larger angle along the fixed structure 1 through the external or internal corner. Moreover, it can be used in conjunction with the fiber-pressing structure 2 to fix the position of the optical fiber 100.

[0076] In some possible implementations, the surface of the fixed structure 1 away from the wall 200 is provided with at least one fiber optic groove, each fiber optic groove being able to accommodate one or more optical fibers 100, so that when the optical fibers 100 are laid along the surface of the fixed structure 1 away from the wall 200, the optical fibers 100 cannot move along the surface of the fixed structure 1.

[0077] In some examples, there are multiple fiber optic slots, which can be arranged in parallel and spaced apart, with the extension directions of the slots passing through the pressure section 21. The parallel and spaced arrangement of multiple fiber optic slots can accommodate multiple parallel and spaced optical fibers 100. Therefore, the optical fiber 100 is better fixed and protected by the fiber optic protector.

[0078] In some possible implementations, the fixing structure 1 is a rectangular plate, and the surface of the fixing structure 1 facing away from the wall 200 is a streamlined surface. The streamlined surface is more conducive to the layout of the optical fiber 100 and is more aesthetically pleasing.

[0079] Combination Figures 1 to 4As shown, in some embodiments, the fiber channel 23 is provided with an opening 23a, through which at least one optical fiber 100 can enter and exit the fiber channel 23.

[0080] With the above arrangement, the optical fiber 100 can be directly inserted into the fiber channel 23 through the opening 23a without having to pass one end of the optical fiber 100 through first. This greatly improves the efficiency of the optical fiber protector and allows for easy addition or reduction of the number of optical fiber protectors in the middle of the already laid optical fiber 100, further improving the efficiency of indoor optical fiber 100 deployment.

[0081] Combination Figures 1 to 4 As shown, in some embodiments, the fiber pressing structure 2 further includes a first connecting portion 22, which extends in the direction of approaching and away from the fixed structure 1, and one end of the first connecting portion 22 is connected to the fixed structure 1, and the other end of the first connecting portion 22 is connected to the pressing portion 21. The extending direction of the pressing portion 21 is arranged at an angle to the first connecting portion 22.

[0082] With the above arrangement, the pressing part 21 is connected to the edge of the fixed structure 1 through the first connecting part 22. The pressing part 21 only needs to be arranged at the end of the first connecting part 22 away from the fixed structure 1. Moreover, by arranging the pressing part 21 and the first connecting part 22 at an angle, the size of the pressing part 21 in the direction perpendicular to the extension of the optical fiber 100 can be extended, so that the pressing part 21 can achieve pressing contact of more optical fibers 100.

[0083] In some possible implementations, the angle between the extending direction of the pressing part 21 and the first connecting part 22 ranges from 60 to 120 degrees. In some examples, the angle between the extending direction of the pressing part 21 and the first connecting part 22 is 60 degrees, 75 degrees, 90 degrees, 105 degrees, 120 degrees, etc.

[0084] In some possible implementations, the first connector 22 is elastic and can provide the pressing part 21 with an elastic force toward the wall 200, so that the pressing part 21 can press the optical fiber 100 tightly against the wall 200, resulting in a better fiber pressing effect.

[0085] In some examples, the fixing structure 1, the first connecting part 22 and the pressing part 21 are integral injection molded structures.

[0086] Combination Figures 1 to 4 As shown, in some embodiments, the first connecting part 22 is located at one end of the pressing part 21, and the other end of the pressing part 21 is spaced apart from the fixing structure 1. The pressing part 21, the first connecting part 22 and the fixing structure 1 together form a fiber channel 23 with an opening 23a.

[0087] In this embodiment, the pressing part 21, the first connecting part 22 and the fixing structure 1 together form a fiber channel 23 with an opening 23a. The optical fiber 100 is laid along the surface of the fixing structure 1 facing away from the wall 200. The opening 23a allows the optical fiber 100 to be inserted into the fiber channel 23. The optical fiber 100 is then pressed between the pressing part 21 and the wall 200, making the operation more convenient and improving the efficiency of the optical fiber protector.

[0088] Combination Figures 1 to 4 As shown, in some embodiments, the extending direction of the first connecting portion 22 is perpendicular to the edge of the corresponding fixing structure 1, the extending direction of the pressing portion 21 is perpendicular to the extending direction of the first connecting portion 22, and the extending direction of the pressing portion 21 is parallel to the edge of the corresponding fixing structure 1.

[0089] In this embodiment, the first connecting part 22 and the pressing part 21 are arranged perpendicularly to each other, and the pressing part 21 is parallel to the edge of the fixed structure 1. The position of the opening 23a is relative to one side edge of the fixed structure 1. The optical fiber 100 laid along the surface of the fixed structure 1 away from the wall 200 can pass through the fiber channel 23 and be pressed against the wall 200 by the pressing part 21.

[0090] Combination Figure 1 As shown, in some embodiments, the fixed structure 1 is provided with fiber pressing structures 2 on opposite sides, and at least one optical fiber 100 is located on the surface of the fixed structure 1 facing away from the wall 200. The two ends of the at least one optical fiber 100 are pressed against the wall 200 on opposite sides of the fixed structure 1 by the two fiber pressing structures 2 respectively.

[0091] With the above arrangement, fiber pressing structures 2 are arranged on opposite sides of the fixed structure 1, which can press down on both ends of the optical fiber 100 laid along the surface of the fixed structure 1 away from the wall 200. Not only can the optical fiber 100 be fixed to the flat wall 200 by using the optical fiber protector, but especially at the external or internal corners, the fixed structure 1 supports and protects the bent section of the optical fiber 100. The fiber pressing structures 2 on both sides press down on both ends of the optical fiber 100, so that the optical fiber 100 is kept in a bent state, and both ends of the optical fiber 100 can extend in the direction close to the wall 200, avoiding the optical fiber 100 from curling up on both sides of the external or internal corners.

[0092] In this embodiment of the fiber optic protector, the fiber compression structure 2 can also be arranged only on one side of the fixed structure 1 (see reference). Figure 4 As shown), they can also be arranged on opposite sides of the fixed structure 1 (see reference). Figures 1 to 3 As shown), the former can achieve the pressure fixation of the optical fiber 100 on a flat wall surface 200 (such as...). Figure 4 As shown), the latter can not only achieve the pressure fixation of the optical fiber 100 on the flat wall surface 200 (as shown), but also... Figure 1 As shown), it can also achieve the pressure fixation of the optical fiber 100 at the external corner (such as...). Figure 2 As shown), and the pressure fixing of the 100° internal angle of the optical fiber (as shown). Figure 3 (As shown).

[0093] Combination Figure 2 and Figure 3 As shown, in some embodiments, the fixing structure 1 includes a first fixing part 1a, a second fixing part 1b, and a second connecting part 1c; the first fixing part 1a and the second fixing part 1b are movably connected through the second connecting part 1c, and a fiber pressing structure 2 is provided on the side of the first fixing part 1a facing away from the second fixing part 1b, and a fiber pressing structure 2 is provided on the side of the second fixing part 1b facing away from the first fixing part 1a.

[0094] With the above arrangement, the fixing structure 1 is a deformable structure composed of a first fixing part 1a, a second fixing part 1b, and a second connecting part 1c. It can conform to the shape of the wall 200 and the corner of the wall. For example, when it is necessary to fix the optical fiber 100 to a straight wall 200, an external corner, or an internal corner, the first fixing part 1a and the second fixing part 1b rotate relative to each other around the second connecting part 1c, presenting different shapes to meet the fiber compression requirements of different wall 200 usage scenarios.

[0095] In some possible implementations, the fiber optic protector includes a straight-angle usage state, a positive-angle usage state, and a negative-angle usage state.

[0096] In the flat use state, the first fixing part 1a and the second fixing part 1b remain flat, and the first fixing part 1a and the second fixing part 1b can be simultaneously bonded to the same flat wall surface 200. The fiber optic protector can fix the fiber optic cable 100 to the flat wall surface 200.

[0097] In the external corner usage state, the first fixing part 1a and the second fixing part 1b rotate relative to each other around the second connecting part 1c, presenting an inner right angle structure. The first fixing part 1a is bonded to one side wall 200 of the external corner, and the second fixing part 1b is bonded to the other side wall 200 of the external corner. The second connecting part 1c is bent on the edge line of the external corner to connect the first fixing part 1a and the second fixing part 1b. The fiber optic protector can fix the fiber optic cable 100 to the external corner.

[0098] In the internal corner usage state, the first fixing part 1a and the second fixing part 1b rotate relative to each other around the second connecting part 1c, presenting an external right angle structure. The first fixing part 1a is bonded to one side wall 200 of the internal corner, and the second fixing part 1b is bonded to the other side wall 200 of the internal corner. The second connecting part 1c is bent on the edge line of the internal corner to connect the first fixing part 1a and the second fixing part 1b. The fiber optic protector can fix the fiber optic cable 100 to the internal corner.

[0099] In some possible implementations, the first fixing part 1a can be separated from the second fixing part 1b along the second connecting part 1c, so that the first fixing part 1a and its connected fiber pressing structure 2, as well as the second fixing part 1b and its connected fiber pressing structure 2, are used as two fiber optic protectors respectively.

[0100] In some possible implementations, the first fixing part 1a, the second connecting structure, the second fixing part 1b, the fiber pressing structure 2 connected to the first fixing part 1a, and the fiber pressing structure 2 connected to the second fixing part 1b are all integral injection molded structures.

[0101] Combination Figure 5 , Figure 6 and Figure 7 As shown, in some embodiments, the fixing structure 1 includes a flared portion 12 and a tubular portion 13, which are coaxially connected and whose axis is perpendicular to the wall surface 200; at least one optical fiber 100 passes through the flared portion 12 and the tubular portion 13 in sequence to pass through the wall surface 200.

[0102] The fiber pressing structure 2 is disc-shaped. The edge of the fiber pressing structure 2 is connected to the edge of the flared mouth 12 through the third connecting part 24. The fiber pressing structure 2 can be flipped around the edge of the flared mouth 12 through the third connecting part 24.

[0103] When the fiber compression structure 2 is installed on the flared opening 12, the fiber compression structure 2 can press and bend at least one optical fiber 100, so that at least one optical fiber 100 extends in the direction close to the wall surface 200.

[0104] With the above arrangement, when the fixing structure 1 is connected to the wall 200, the tubular part 13 is inserted into the wall 200 at an angle perpendicular to or at an angle to the wall 200, while the flared part 12 remains outside the wall 200, with its circumferential edge fitting against the wall. The fixing structure 1 can be anchored using the friction between the tubular part 13 and the wall. The optical fiber 100 can pass through the flared part 12 into the tubular part 13 and extend along the inner edge of the tubular part 13 until it passes through the entire wall, thus achieving the through-wall installation of the optical fiber 100. A disc-shaped fiber compression structure 2 is arranged in the flared part 12. The fiber compression structure 2, in conjunction with the flared part 12, can compress the optical fiber 100 extending axially along the flared part 12 into a radial extension along the flared part 12. Moreover, the optical fiber 100 can be bent along the inner curve of the flared part 12 at a large bending angle, without the risk of breakage.

[0105] In some possible implementations, the tubular part 13, the flared part 12, the third connecting part 24, and the fiber pressing structure 2 are all integral injection molded structures.

[0106] Combination Figure 7 and Figure 8As shown, in some embodiments, the fiber pressing structure 2 is further provided with a first snap-fit ​​part 25 and the flared mouth part 12 is provided with a second snap-fit ​​part 121. When the fiber pressing structure 2 covers the flared mouth part 12, the first snap-fit ​​part 25 and the second snap-fit ​​part 121 snap-fit ​​each other.

[0107] With the above arrangement, when the fiber-pressing structure 2 is covered by the horn-shaped opening 12, the first snap-fit ​​part 25 and the second snap-fit ​​part 121 snap-fit ​​the fiber-pressing structure 2 onto the horn-shaped opening 12, which can prevent the stress of the optical fiber 100 from pushing the fiber-pressing structure 2 open, and at the same time provide fiber-pressing support for the fiber-pressing structure 2. Moreover, the snap-fit ​​connection between the fiber-pressing structure 2 and the horn-shaped opening 12 is simple to operate and can be disassembled, making it more convenient to use.

[0108] Combination Figure 7 and Figure 8 As shown, in some embodiments, the fixing structure 1 further includes anchoring fins 15, which are located on the outer wall of the tubular portion 13.

[0109] With the above arrangement, the tubular part 13 can be anchored to the wall using the anchoring fins 15 on the outer wall, thereby improving the connection reliability between the fiber optic protector and the wall.

[0110] Combination Figure 7 and Figure 8 As shown, in some embodiments, at least one of the fiber pressing structure 2 and the flared mouth portion 12 is provided with a support portion 26. When the fiber pressing structure 2 covers the flared mouth portion 12, the support portion 26 supports the fiber pressing structure 2 and the flared mouth portion 12, so that a fiber passage space parallel to the wall surface 200 is formed between the fiber pressing structure 2 and the flared mouth portion 12.

[0111] To prevent the fiber compression structure 2 from being overly compressed, a support portion 26 is arranged between the fiber compression structure 2 and the flared mouth portion 12. The support portion 26 can support the two to form a fiber passage space, from which the optical fiber 100 can extend outward along the direction close to the wall surface 200.

[0112] Combination Figure 7 and Figure 8 As shown, in some embodiments, the fixing structure 1 further includes a notch 14 that extends axially along the flared mouth portion 12 and the tubular portion 13 and passes through the flared mouth portion 12 and the tubular portion 13, respectively.

[0113] When the fiber pressing structure 2 is placed on the flared mouth portion 12, the first snap-fit ​​portion 25 is inserted into the notch groove 14 on the flared mouth portion 12 and snaps into the notch groove 14, and the notch groove 14 on the flared mouth portion 12 is formed as the second snap-fit ​​portion 121.

[0114] With the above arrangement, through notches 14 are provided on the flared portion 12 and the tubular portion 13. These notches 14 allow the fixing structure 1 to be easily fitted onto the middle section of the optical fiber 100, which helps improve the efficiency of the optical fiber protector. Moreover, the notches 14 provide a certain deformation space for the tubular portion 13 and the flared portion 12, reducing the difficulty of inserting the fixing part into the wall.

[0115] In addition, the notch 14 can also be engaged with the first snap-fit ​​part 25 to realize the function of the second snap-fit ​​part 121, eliminating the need to arrange the second snap-fit ​​part 121 separately, which helps to simplify the structure of the fiber optic protector and thus reduce the processing cost of the fiber optic protector.
